JOHN H. POOLE, OF RANDOLPH, MASSACHUSETTS, ASSIGNOR OF ONE-HALF TOCHARLES PRESCOTT, OF SAME PLACE.

CHANNEL-OPENING GUIDE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 549,393, dated November5, 1895.

Application filed August 10, 1895.

To all whom it may concern:

Be it known that I, JOHN H. POOLE, of Randolph, in the county of Norfolkand State of Massachusetts, have invented certain new andusefullmprovements in Work Supports or Guides for Boot and Shoe SoleSewing Machines, of which the following is a specification.

This invention relates to the work rest or support used in boot and shoesole sewing machines, and particularly machines for sewing channeledouter soles to the welts of welted boots and shoes,,said rest beingconstructed to enter the stitch-receiving channel in the outer sole andto properly guide the work during the operation of stitching the sole tothe welt.

The invention has for its object to provide an improved work rest orguide adapted to enter. the channel, raise the channel-lip or flap, andhold it out of the path of the needle.

To these ends the invention consists in the improvements which I willnow proceed to part of this specification, Figure 1 represents aperspective view of my improved workguide engaged with asole. Fig. 2represents a top View of the same. Fig. 3 represents an edge view. Fig.4 represents a perspective view in a different position. Fig. 5represents a section on line 5 5, Figs. 1 and 2. Fig. 6 represents asection on line 6 6, Fig. 2.

The same letters and figures of reference indicate the same parts in allthe figures.

I11 carryingout my invention I construct a work-guiding arm a, having ashank a, adapted for attachment to asuitable part of a sole-sewingmachine, and a work-supporting face a which is in position to bear onthe outer soleb outside of the channel Z) Serial No. 558,816. (Nomodel.)

it extends across the channel, as shown in Figs. 2 and 6, one edge 2 ofthe plow being in contact with or near the outer edge of the channel,while the other edge 3 bears against the inner surface of thechannel-lip 17 The edge 3 of the plow serves to raise the channel-lipwhen the sole is moved in the direction indicated by the arrow, the lipbeing held raised at substantially a right angle with the sole by thebase of the plow. A recess c is formed in the arm a, said recessextending through the base or wider end of the 'plow and having a mouthformed in the edge 3. Fire said recess is of sufficient size to permitthe awl and needle of the machine to move freely through the arm, andits mouth is preferably contracted to prevent the channel-lip fromentering the recess.

It will be seen that the plow containing the needle-receiving recess andconstructed to easily and gradually raise the channel-lip and hold itout of the said recess enables the work to be stitched without liabilityof the needle encountering or passing through the channel-lip. It willalso be seen that the channel is raised so naturally and gradually bythe plow that it does not require to be hammered back against theadjoining surface of the sole at any point, but is raised from thechannel wholly by the plow and therefore may be easily replaced in thechannel.

I claim- A channel-opener for boot and shoe sewingmachines, comprisingan arm or rest having a sole-supporting face, a wedge-shaped plowprojecting from said face, and a needle-receiving recess extendingthrough the arm and through the rear or wider end of the plow, saidrecess having a mouth extending through one edge of the plow.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses,'this 7th day of August, A. D.1895.

JOHN H. POOLE.
